Aim: Recent scientific attempts of our department on several 5-arylidene-1,3-thiazolidin-4-one derivatives have yielded some derivatives with antiviral and anticancer activities and also an increasing number of studies on these type of compounds encouraged us to pursue our efforts to synthesize 5-arylidene-1,3-thiazolidine-4-ones.

Materials and Method: Sulfanilamide was selected as the starting compound to synthesize 5-arylidene-1,3-thiazolidine-4-ones within context of our thesis. Through the reaction of sulfanilamide with chloroacetyl chloride, 2-chloro-N-[4-(sulphamoilphenil)acetamide [1] was gained. 1,3-Thiazolidine-4-one ring system [2] was gained by refluxing compound 1 and ammonium thiocyanate in ethanol. Targeted arilidene compounds [3-14] were synthesized by the reaction of compound 2 with appropriate aromatic aldehydes in sodium methoxyde solution.

Findings: Purity of the synthesized compounds is confirmed by elementel analysis data. Their structures were elucidated by the use of their IR, ¹H-NMR and ¹³C-NMR spectral data.

Results: The synthesized compounds are considered to be evaluated for their antiviral and anticancer activity.

Keywords: 1,3-Thiazolidine-4-one, 5-arylidene-1,3-thiazolidine-4-one, sulfanilamide, anticancer activity, antiviral activity.
